Choose 5mm to 8mm thick acrylic sheets for outdoor furniture. Table Top Cover. A plexiglass sheet of 2mm to 4 mm thickness is suitable for table top covers. Greenhouse. For a greenhouse, 8mm thick acrylic sheets are recommended. Floating Shelves. Plexiglass thickness in the range of 20 to 30mm is suitable for acrylic floating shelves. Aquarium.
Is it possible for UV light to pass through plexiglass? It may not be possible to totally avoid colour fading or discoloration due to UV plexiglass but it can block up to 98 percent of harmful UV light from reaching the surface. The UV protection provided by this acrylic sheeting is limited to wavelengths less than 400 nanometers in length.
For instance, in Figure 6 b, PECA-5-2 demonstrates about 17% transmission at 375 nm compared to PECA-2.5-1 that transmits about 35% at the same wavelength. Table 2 shows comparisons among published works on UV blocking capabilities of various transparent polymer films including the present study.
Look at side of thru plastic layer. change sides of panel. The UV side is the side where the plastics glows the most. The Non UV side will not glow much at all. Think a 365 nm would do better since the sheets reject UV beginning at 400 and the 395 nm flashlights have some output to at least 425 nm.
Plexiglas® sheet absorbs short wavelength ultraviolet (UV) energy, but transmits most of the long wavelength UV (those wavelengths just short of the visible region). The total uv energy absorbed is about 65%.
UV radiation has both positive and negative effects. Positive effects of UV radiation include warmth, light, photosynthesis in plants, and vitamin D synthesis in the human body. However, too much exposure to UV damages skin cells and leads to wrinkled and patchy skin, cataracts, and even skin cancer. Ultraviolet (UV) radiation is often divided
We are familiar with the effects of UVA and UVB, however not UVC. There have been no reports to us of UVC light being an issue with any UV-blocking acrylic application during our last 101 years in business. If more information is critical to your project, we recommend you call in and we will find the answers for you. 1-800-474-3688. Delete
